How we scored it
AgCl inorganic mineral salt → 1.0 (minerals and inorganic salts are natural origin)
What counts. ISO 16128-2 scores the atoms that remain in the final ingredient. Reagents, solvents, catalysts and protecting groups used during manufacture leave no mass behind and are not counted.
Where it comes from
Manufactured by precipitating a silver salt with a chloride source, or refined from silver ore. As an inorganic mineral salt it is natural origin though not renewable.
In plain English
A simple mineral salt of silver used as a preservative to limit microbial growth. It is an inorganic compound, so under natural-origin rules it counts fully as mineral, not petrochemical.
CosIng definition: Silver Chloride is the inorganic salt that conforms to the formula:
Structure
chlorosilver
